• Are the power cord and plug in good conditi-
on (solid, without fraying or other damage)?
• Avoid the use of long extension cords. The ex-
tension cords you use must always be earthed.
• A grinding wheel is a brittle tool piece. The
stone is not resistant to knocks.
• Always grind on the front edge of the grinding
wheel, and never on the side of the grinding
wheel. Never fit a cracked grinding wheel.
Replace it immediately, as the high rotational
speed could cause the stone to fly apart, cau-
sing a serious accident.
• Always wear safety glasses when grinding.
• Never grind without the cover fitted over the
grinding wheel.
• Always fit the grinding wheel cover and tool rest
tightly, and with the correct clearance.
• Never allow more than 1-1.5 mm clearance
between tool rest and grinding wheel.
• Only use the grinding wheel for the work it was
designed for (for example sharpening tools),
and NOT for heavy construction work.
• The following information must be available,
before you fit any new grinding wheel:
• Details about the manufacturer.
• Binding material.
• Dimensions.
• Permissible rotational speed.
• Never ream out the hole in a grinding wheel to a
larger diameter.
• The maximum rotational speed of the grinding
wheel should never be allowed to exceed the
maximum speed given for the wheel.
• Never use any grinding wheel that is damaged
or deformed.
• In order to be able to grind safely, the machine
must be firmly bolted to a workbench.
• The tool rest should be replaced whenever the
width of the tool rest measures less than 20 mm.
• The recommended depth of the recess in the
flange (T) is 2 mm and the diameter of the
spindle hole is 10 mm (see Fig. B).
• Always keep the cord away from the moving
parts of the machine.
• In the case of locking, switch the machine off im-
mediately and remove the plug from the mains.
• Compare the maximum number of revolutions
allowed of the accessories with the number of
revolutions of the machine.
• When you put the machine away the engine
must be switched off and moving parts must
have reached a standstill.

• Never attach an assembly spanner to your ma-
chine with a piece of string or anything similar.
• Never use the axle locking button if the machine
is operating.
• Make sure that the spring chuck diameter is the
same as the axle diameter of the accessory.
• Use a clamping device for securing the work
piece.
• Keep your hands away from the work piece.
Whenever using the machine
• Check that the switch is NOT in the 'ON/1'
position before connecting the machine to the
power supply.
• Always keep the power cord out of the way of
the tool's moving parts.
Immediately switch off the machine when:
• The plug or power cord is defective or damaged.
• The switch is defective.
• You smell smoke or burning insulation.
Electrical safety
When using electric machines always observe the
safety regulations applicable in your country to
reduce the risk of fire, electric shock and personal
injury. Read the following safety instructions.
Always check that the voltage of the power
supply corresponds to the voltage on the
rating plate label.
Replacing cables or plugs
Immediately throw away old cables or plugs when
they have been replaced by new ones. It is dangerous
to insert the plug of a loose cable in the wall outlet.
Using extension cables
Only use an approved extension cable suitable
for the power input of the machine. The minimum
conductor size is 1.5 mm
